Answer:

y = 45,121,040×1.027^t

Step-by-step explanation:

An exponential growth equation is generally of the form ...

 value at time t = (initial value)(growth factor)^t

where the growth factor is the multiplier for a period equal to one time unit.

Here, the initial value (in 2014) is 45,121,040. The growth factor is given as 1.027 (2.7% added per year), and we can define t as the number of years after 2014. Then our equation is ...

 y = 45,121,040×1.027^t . . . . where t = years after 2014

Answer:

Step-by-step explanation:

The sum or difference modeled by the algebraic tiles is (-x²+2x+3) + (-x²-2x-1) = -2x²+2

From the complete question, we have the following expressions:

(-x²+2x+3) and (-x²-2x-1)

Add both expressions

(-x²+2x+3) + (-x²-2x-1)

Expand

-x²+2x+3 -x²-2x-1

Collect the like terms

-x² -x² + 2x - 2x + 3 -1

Evaluate the like terms

-2x²+2

Hence, the sum or difference modeled by the algebraic tiles is (-x²+2x+3) + (-x²-2x-1) = -2x²+2

Step-by-step explanation:

The chords ac and db are intersecting chords, and the length of line segment db is 16 units

The given parameters are:

ah = 20 - x

hb = 12 - x

dh = x + 4

hc = x

Start by calculating the value of x using the following intersection chord equation

ah * hc = dh * hb

So, we have:

(20 - x) * x = (x + 4) * (12 - x)

Solve for x

x = 4

The length of segment db is calculated using:

db = dh + hb

So, we have:

db = x + 4 + 12 - x

Substitute 4 for x

db = 4 + 4 + 12 - 4

Evaluate

db = 16

Hence, the length of line segment db is 16 units

Step-by-step explanation:

a) The infinite series in sigma notation is described by this expression:

[tex]y = \sum \limits_{i=1}^{\infty} \frac{1}{i\cdot (i+2)}[/tex]     (1)

b) The explicit formula for the n-th partial sum is represented by the following expression:

[tex]y = \frac{1}{i\cdot (i+2)}[/tex], i ∈ [tex]\mathbb{N}[/tex]     (2)

An infinite series is monotonous when it is bounded, that is, when the limit of the infinite series exists. In this case, we have an evidence of monotony in the denominators of the terms of the given series. In two consecutive terms, the latter always have a denominator greater than the former.

a) The series in sigma notation is now described below:

[tex]y = \sum \limits_{i=1}^{\infty} \frac{1}{i\cdot (i+2)}[/tex]

b) The explicit formula for the n-th partial sum is defined by the expression within the sum, which is now presented below:

[tex]y = \frac{1}{i\cdot (i+2)}[/tex], i ∈ [tex]\mathbb{N}[/tex]

Answer:

$73.80

Step-by-step explanation:

First we will find Kevin's hourly wage. We can do this by dividing his total pay by the number of hours he worked.

$492 / 20 hours = $24.60/hour

Now we can find how much he will make the next week.

$24.60/hour * 3 hours = $73.80.

If Rob receives $4,585.75 in annual dividends, the number of shares of Agram Imports that Rob owns is D. 441 shares.

A dividend is the distribution of cash or stock that a company makes to its stockholders periodically.

Dividends are usually based on a dividend payout ratio, determined by the Board of Directors of the company.

                                       Dowc Beverage Co.     Agram Imports

Dividend per share                 $6.52                               $5.15

Number of shares                    x                                     x+ 86

Number of shares                 355 (441 - 86)                  441 (355 + 86)

Total dividend received      $2,314.60 ($4,585.75 - $2,271.15))  $2,271.15

which is equivalent to $2,314.60 ($355 x $6.52)

Assuming total shares from Agram Imports to be 441, the total dividends will be $2,271.15 ($5.15 x 441), and, the dividend from Dowc Beverage Co. will be $2,314.60 and the number of shares will be 355 ($2,314.60/$6.52), which is 86 less than the shares in Agram Imports.

Thus, if Rob receives $4,585.75 in annual dividends, the number of shares of Agram Imports that Rob owns is D. 441 shares.

Answer:

Answer would be B

Step-by-step explanation:

First, A doesnt make sense, since it isn't a ineqality.

C doesnt make sense because if 5 is subtracted form a number n, it is -2, not 2.

D doesnt work because 5 less a number (-5) is not 2, it is -2.

So B works, because the difference between n and 5 (n-5) is -2.

Explanation:

Choice A simplifies to 9n-8 after combining the like terms -7n+16n to get 9n

Choice C simplifies to 9n-8 for similar reasoning. The n+8n turns into 9n

This shows choices A and C are equivalent to choice D. Choice B isn't the same because 9(n-8) = 9n-9*8 = 9n-72. Use the distributive property.

Answer:

B. 9(n - 8)

Step-by-step explanation:

- 8 - 7n + 16n

-8 (-7n + 16n or 16n - 7n)

-8 + 9n

9n - 8

9(n - 8)

9n - 72

n - 8 + 8n

Check the picture below.

now, we're making an assumption that, the two blue shaded region are equal in shape, and thus if that's so, that area above the 14 is 6 and below it is also 6, 14 + 6 + 6 = 26.

so hmm if we simply get the area of the trapezoid and subtract the area of the yellow triangle and the area of the cyan triangle, what's leftover is what we didn't subtract, namely the shaded region.
